SPECIFICATION forming part of Letters Patent No. 541,103, dated J une 18, 1895.

l Application led July 28,1894. Serial No. 518,861v (No model.)

To all whom it may concern: Y

Be it known that We, JOHN NV. MABIN and DEO C. MUNGER, citizens of the United States, residing at Maiden Rock, in the county of Pierce and State of Wisconsin, have invented newand useful Improvements in Gluing- Machines, of which the following is a specification. Y

Our invention relates to improvements in gluing machines and pertains especially, first, to devices for applying melted glue to the match edge of boards; second, to mechanism for feeding the boards to the gluing device; third, to mechanism for feeding the glued boards together with boards that are not glued, into an appropriate position to be driven together; fourth, to means for driving or pressing the boards into union,all as hereinafter described and set forth.

Our invention is designed for use principally, in the manufacture of boxes and similar work, Where the material used for any given period is of uniform length.

The object of our invention is to automatically apply the glue and unite the pieces to produce a material of sufficient width for the purposes of this class of manufacture.

In the drawings, vFigure I is a side elevation of our invention viewed from the side opposite that of the drive-wheel and the connecting-belt of the glue-wheel. Fig. II is a view of the actuating-levers in elevation with the lower or front end of the frame removed on the section line 2 2 of Fig. I. Fig. III is a perspective of the frame top, viewed from the lower end, showing the grooved and tongued material as it is piled upon the frame preparatory to being acted upon by the machine. This view also shows two of the pieces united under the head as they are immediately after striking of the hammer. Fig. IV is a crosssection of the frame-top, drawn on the line 3 3 ot' Fig. I. Fig. V is a vertical section drawn on the line 4 4 of Fig. I, showing the construction of the glue-wheel. Fig. VI is a cross-section of the top, drawn on the line 5 of Fig.

' I, showing one of the grooved pieces after it iSO has been passed over the glue-wheel and as it is delivered at the side of the head-supporting partition opposite the tongued pieces preparatory to being fed underneath the head.

Like parts are referred to throughout by the same reference-letters.

A refers to our gluing machine frame, the top of which forms a very open or spreading trough inclined toward the front or dischargeV end.

B and O refer respectively to pieces of socalled matching, being boards of even length, provided with matched edges as commonly used in the manufacture of boxes.

D refers to a head so-called, which consists of a right-angledplate, having a vertical porltion extending transversely of the frame, and a narrower horizontal portion extending forward from the bottom of the vertical portion, as shown clearly in Fig. III. The head is supported by a raised partition N suiiiciently above the frame A to allow the pieces of matching to pass singly beneath it, on each side of the partition.

Gis a revolving glue-wheel located in a glue tank M, with its upper edge projecting through a slot in the rear of, and slightly to one side of the partition N.

H is a sliding feed frame, located in the rear of the head and adapted to reciprocate longitudinally on the upper surface of the frame A. This feed trame is composed of the side pieces H', H', the guide bars H", and the connectin g cross strips H the connecting mechanism of the actuating parts being attached at the projecting rear end of the guideV bars H", as hereinafter described.

The grooved pieces B are piled with the match edge down upon the supporting bar K, .which is attached longitudinally to the frame H, with the outer edge raised, as shown in 'l Fig. IV. Retaining brackets I, I projecting upward from the frame Aare adapted to support the pile of matched pieces upon the bar, the bracket I being adapted to release the bottom piece, which is pushed out from under the pile by the follower J, during the forward movement of the feed frame. The released piece, resting in an inclined position on the bar K, is carried down toward the head over the projecting edge of the glue Wheel G, and the `revolutions of the wheel carry the glue from the tank into the groove, the piece then passing to one side of the partition N. The reverse movement of the feed frame draws the ICG bar K out from under the glued piece, while the momentum of the piece carriesit forward till it strikes against the head and drops in the rear thereof, with the match edge toward. the partition. The pieces C are piled upon thefopposite side of the partition N, with thematch edge toward the partition and the side pieces H H of the feed frame H, are adapted, with its forward movement, to push the glued piece B simultaneously with the bottom piece C, past the partition N, and underneath the head, wheretheir end'srare trued` upby strik.- ing against the raised transverse ilangeO. on the pressure bar P, hereinafter described.

It will be observed, that when the machine is-in continuous operation, one of the pieces B is always being fed down over the glue wheel, simultaneously wit-h the'pushing of the preceding piece B, together with the bottom piece C, under the head, so` that each reverse mo'vement of the frame leaves a freshly glued piece in the rear of the head, ready tobe fed un` derneath itwith the next forward movement.

It. will be also observed, that after the-pieces v ,is prevented from slipping forward by thefiange P, attached to the connect-ing metallic cross strip-A of the frame top. The rearend of this pressure bar is adapted to beelevated by theaction of the machinery topress the material intoa true horizontal positionagainst the under surface of the head, as shown in Fig. III. The block F is simultaneously brought to bear against the piece C, and the hammerstrikes the piece B, thus driving them together.

To assist in discharging the united.' pieces, We have provideda traveler Q, which consists of a flat plate resting in guides underneath the pressure bar, and provided with raised ilangesfR, R, projecting above the pressure bar on each side thereof.

traveler, with the flanges RR is drawn rearward by the machinery partially underneath the united pieces, and when the pressure bar drops to its normal position, they rest upon the flangesand are held by them above the [lange O.v The pieces next fed. under the head, strike against the rear of the united pieces and push them over the flange O, thus discharging them f-rom the machine. The pieces last fed, also strike the ends of the flanges R,Rand push them to therear-of the flange O, the'movement of the pieces being r the piece adjacent to it, simultaneously with t-heupward movement of the pressure ha? and preparatory to the striking of the haml l Iller'.

X and Z, strikes against the projection e`0f While the pressurebar is elevated as above described, thisl V checked bythe latter flange, thus leaving them in position to be driven together, as heretofore described. Y

The parts above described are actuated by means of the driving shaft S, connected with the source of power. The revolutionsofvthe shaft S are communicated to the glue wheel by means of the beltT and the reciprocal motion ot the feed frame H is obtained by means of the crank U, crank-arm U and lever V, the latter being pivotally connected to. the feed-frameat its upper end, and to the adjusting bar W at its lower end.

The hammer E is actuated by means of a j,

system of levers X, X and Xf being attached to the end of thelower level' X. Thevcranlrarm U vis' extended somewhat beyond 'the point of attachment to the crank* and is adapted to strike underneath the lever X, thereby lifting the con nected-end of the lever,

and throwing the hammer back in a pos- `1 u tion for striking. At the same time the`aet-' l uating spring Y is distended by the dowlb' ward movement of that end of the lever-Xi l to' which the hammer is attached, and causes Ward? projecting angle of the lever Z, 'which actuat-es the pressnrebar P and elevates-the bar simultaneously wit-hthebackward movement of the hammer E.

ing through the angle of' the lever Z, iseon nectedv tothe post c of the block Fjby means of the strap d, whichispivoted atits respect The bar a, pivotedl'o j the supporting-pcst' ofthe frame and projpctive ends to the post c and thebar a. The

'post c being pivotally attached to its 10W" end to the-frame, the elevation of the leverZ is thus adapted to also elevate the bar aand to draw the block Fin-towardy and against The crank U,`after passing the levers the lever f which actuates the traveler Q10 draw the flanges R R underneath the piec, as heretofore explained, while the lat-ter are elevated by the pressure bar` P;

means the hammer and block can be madeto strike thepieces in the center `and drive them together with certainty throughout their frame-is regulated by varying the point'of The'hammer E and block F areboth can ,l ble of adjustment to adapt them to piecesof different lengths, by means of their respective posts being constructed in sections, thel up i.

attachment of the crank-arm U to the lever V, thus adapting the machine to pieces of any given length.

By means of theintervening spring lin the lever Z, the pressure bar P is elevated elastically, thus obviating the danger of breaking the parts by means of too great pressure.

The glue wheel G may be composed of the two disks k, between the edges of which a piece of felt or similar material m is inserted, the disks being then rigidly bound together on the shaft fn. The felt projects slightly, forming a rim which easily adjusts itself to the groove in the pieces passed over it and glues it thoroughly. The glue may be kept hot by means of a coil of steam pipes o, arranged in or about the glue tank.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
